    Well, this was a great idea until you find that this is also used for
    linking the intermediate vmlinux objects for kallsyms, and kallsyms
    uses weak (== undefined) symbols:

    LD .tmp_vmlinux1
    .tmp_vmlinux1: error: undefined symbol(s) found:
    w kallsyms_addresses
    w kallsyms_markers
    w kallsyms_names
    w kallsyms_num_syms
    w kallsyms_token_index
    w kallsyms_token_table

    Maybe kallsyms needs to provide an empty object with these symbols
    defined for the first linker pass, instead of using weak symbols?
